The footage appears to precede the interview in which Rivera dismissed the protesters as "vandals" and accused them of "looking for trouble".

The interview, in which Maryland state Sen. Majority Leader Catherine Pugh asks the media to stop "inciting people", shows the same man step in front of the camera, to which Rivera replies "you're making a fool of yourself".

In the footage that has emerged, the demonstrator can be seen talking to Rivera before the broadcast.

The unidentified man tells the reporter: “I want you and Fox News to get out of Baltimore City".

"You are not here reporting about the boarded up homes and the homeless people... You’re not reporting about the poverty levels up and down North Avenue".

"You're not here for the death of Freddie Gray.. but you're here for the black riots that happen".

Asking the cameraman to stop filming, the man said "This is not for YouTube... I want the white media out of Baltimore City until you're here to report the real story".

"You got this TV camera protecting you from all these black folk... we are the ones that need protecting".

In the footage, the man can be heard to plead "talk to me. I just want a conversation", while Rivera attempts to walk away. "I want to talk to you off camera. I want all the cameras off".
